They don't care much about sequence, but see J.O.Skip Robinson reply.

Great Martin! That was a
Thanks for the feedback. That Redbook I mentioned was able to answer most of my
questions. We will be enforcing an IPL order for our Sysplex, in particular the
first LPAR that is brought up. This will be done to ensure the structures built
in the coupling facility will always be built by a

I guess I am missing something. Unless the CF's are being recycled, there are
no structures to be (re)built. And even so, all lpars should be using
Yes… my understanding from the documentation is that the CF structures once
built will remain intact for the duration of CF LPAR run. Not sure about the
“disposition of delete” comment… I would have look into that.
These LPARs are not in a Parallel Sysplex. We have an existing Sysplex with two

Sorry for the confusion... these LPARs are in a Parallel Sysplex (using CF),
but not utilizing many of the Parallel Sysplex features. Reading through the
documentation... I guess it might fall under the description of BronzePlex.

This book has been suggested:

IBM z/OS Parallel Sysplex Operational Scenarios
It has an excellent chapter (chapter 3) on IPL order.
